Specification of Letters Patent.

Patented Aug. 16, 1921.

Application filed August 13, 1919. Serial No. 317,168.

To all whom it may concern Be it known that I, JULns BYRON TAY- LOR, acitizen of the United States, and a resident of Toledo, in the county ofLucas and State of Ohio, have invented a certain new and useful Gearing;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a. part of this specification.

This invention relates to control means for gearing of the automaticreversing type, such, for instance, as is used in connection with theoperation of a washing cylmder of a washing machine.

The primary object of my invention is the provision of improvements inthe automatic control for the reversing means and in the manuallycontrolled stop means for such mechanism disclosed in former UnitedStates Letters Patent, No. 1,170,707, dated February 8, 1916, whereby amore perfect and satisfactory operation of the mechanism is obtained.

The invention is fully described in the following specification, andwhile, in lts broader aspect, it is capable of embodiment in numerousforms, a. preferred embodiment thereof is illustrated in theaccompanying drawings, in which,

Figure 1 is a front elevation of a gearing embodying my invention withparts broken away and with the shiftable clutch member in neutralposition. Fig. 2 is a central vert1- cal section of the mechanism withthe connected operated parts fragmentarily shown. Fig. 3 is an enlargedperspective vlew of the automatic reversing link, and Fig. 4 1s an endelevation of the manually controlled clutch shifting member inengagement with a stop member and shown in released position by dottedlines.

Referring to the drawings, 1 s a drive shaft provided with a suitabledrive means. This shaft is journaled in bearings on the machine atopposite sides of the circular casing 2, which is suitably secured tothe front of the machine and incloses the reversing gearin Upon theshaft 1 is a sleeve 3 movable longitudinally thereof but rotatabletherewith by reason of a pin and groove 3 or other suitable connectiontherebetween. At each end of the sleeve 3 and rigid therewith is aclutch member 4: adapted to engage a corresponding clutch member 5rigidly connected with or forming a part of bevel pinions 6 loose uponthe shaft 1. It will be seen that as the sleeve is moved longitudinallythe members of one or the other of the clutches will be operativelyconnected according to the direction in which the sleeve is shifted.

driven shaft 7, .at right angles to the shaft 1, is journaled in theinner side of the case 2 and is connected at the end thereof most remotefrom the shaft 1 to the member 8, which it is desired to operate, which,in the present instance, is the washing cylinder of a washing machine.At its other end, the shaft 7 is fixedly connected to the center of adish-shaped gear wheel 9, the beveled teeth of which are arranged aroundits outer edge and mesh with both pinions 6. Upon the face of the gear 9next to the sleeve .3 is a spiral groove 10 extendin from near itscenter to near the rim of the gear, the bottom of the groove at itsouter end sloping outwardly, as shown at 11, to provide a slightlyelevated return communication with the groove of the next convolution.The purpose of this will be hereafter described.

The groove 10 is engaged by a pin 12 projecting from one end of thelever 13 fulcrumed, asat 14, upon a bracket 15 bolted or otherwiserigidly secured inside of the casing 2 at its lower side. The oppositeend of the lever 13 is pivotally connected at 16 with one end of a link17 the other end of which projects transversely therefrom and isprovided with an elongated longitudinally extending slot 1 A lever 19 isfulcrumed to the bracket member 15 or casing 2 at 20 and is providedwith a pin 21, which projects into the slot 18 ofthe link 17 forpredetermined lost motion movement therein to permit a limited rockingof the lever 19 without effecting a movement of the link 17, or viceversa.' The lever 19 is recessed at its inner or fulcrumed end, as at22, to loosely receive the lower end of a lever 23 fulcrumed, as at 24,upon the bracket 15. The upper end of the lever 23 is notched tostraddle or embrace a peripheral rib or ring 25, which encircles and isrigidly carried by the clutch sleeve 3 intermediate its ends.

A weight 26 is carried by the lever 19, and

through bosses rod 31 carries a for limited .tion as shown in .33 topermit adjustment away from each other to adapt them to fit the in thepresent embodiment of the invention this weight is pivotally suspendedfrom'the lever near its upper or free end and has a recess in its sideto receive the lever with the sides of the recess forming'stops whichlimit the swing of the weight relative to the lever.

The permissible movementof the pin 21 of the weight lever 19 within thelink slot 18 longitudinally thereof is controlled by stop-pins 27 and28, which are inserted or lugs 29 and 30 at the inner and outer ends,respectively, of the slot 18. The pins 27- and 28 are adjustable towardand away from each other lengthwise of the slot 18 and coact with thepin 21 to limit the length of either swinging stroke of the lever 19.Screws 27 and 28 are threaded in the respective bosses 29 and30 toengage and secure the stop-pins 27 and, 28 in adjusted positions. 7

The manual control for shifting the clutch sleeve 3 comprises a rod31,'which ismounted for .longitudinal movements in the. case 2 parallelto the shaft 1, and in the present instance, at the upper side thereof.The sleeve 32 within the case 2, rotary movements, and this sleeve hasa. forked arm 33 extending downward therefrom with-the forks thereofdisvposedat opposite sides of the ribor ring 25 on the sleeve 3 and withthe ends of the fork arms bifurcated to straddle the sleevej3. The

rockingmo-vements of the rod 31 relative to' the sleeve 32 are limitedby a pin 34, which projects through the rod and has engagement at itsopposite endswith opposite sides of a stop lug 35, on the sleeve end, asbest shown in Fig. 4. One end of the rod 31 is provided with a lateralextension 36, which, when disposed in the reclining position shown inFigs. 1 and at, rests on a catch finger 37 that projects horizontally inan adjustable manner from a stationary casing or frame part 38. Thisfinger 37 has a notch, in its top surface into which the angled end orextension 36 of the rod 32 drops when in register therewith. The notchinthe catch finger 37 is so disposed that when the rod extension, isengaged therewith the clutch sleeve 3 is in itsneutral or released posi-Fig. 1. WVhen the rod has been rotated to place the extension 36 in theupright dotted line position shown in Fig. 4, it will maintain suchposition and permit a continuous automatic operating of the gearinguntil the control rod has been turned by hand to'permit its extension 36toengagxe thenotched catch finger 37.

screw 39 connectsthearms of the fork thereof toward or rib 25 and tocompensate for wear.

The operation of the mechanism is as follows: To start the machine, theoperator Should the link 17 or other tical, plane,

into engagement 9. This movement of the gear 9 causes movement of theupper end of the lever 13 toward the center of said gear due to the pin12 of said lever traveling in the spiralv groove 10. This movement ofthe lever imparts a pull to the left on the link 17, the pin 28 of whichis now in engagement with the pin 21 on the lever 19 so as to graduallymove said lever toward upright position. WVhen the lever 19 has beenmoved sufficiently to pass avercause it to quickly rockto the extent ofits movement to the left, thereby operating the lever 23 to shift theclutch sleeve 3 out of engagementwith the left hand pinion 6 and withthe right hand pinion 6. The right hand pinion 6, which is now the livepinion, will cause a. driving of the gear 9 in clockwise direction so asto cause an'outward traveling of the pin 12 in the groove 10.1 When thelever 13 has been rocked a predetermined distance in the outwardmovement of the pin 1-2, the pin-27. on the link 17 will have engagedand moved the lever 19 past vertical position to permit its weight tothen act to; quickly operate the lever to effect a shifting oftheclutchsleeve to effect a reversing of the movement of the gear 9.This is repeated solong as the control rod. 31 is left in its operativeposition. v When it is desired tojstop' the machine the rod 31 is turnedto permit the extension 36 thereof to rest on the catch finger 37 andthe actionof the weight 26 will r its neutral or released position, asshown in Fig. 1, will drop into the catch notch of the finger 37 andhold the parts against further movement.-

The purpose of the pins 27 and 28 in the link 17 isto not only maintainan accurate operation of the parts, but also to permit an adjustment ofeach end wall of the link slot to effect an early or late tripping ofthe weight lever-19 at each inward and outward stroke of thespiral'groove engaglng end of thelever .13 so that a, reverse movementof thecylinder 8 or actuated member may be obtained: at the end of adesired or predetermined number. of revolutions thereof,

which is found to be quite an important item in machines of thecharacter described.

Control parts become broken so that the clutch sleeve 3 is not shiftedupon an outward movement of the pin 12, in the spiral groove 10, thegear 9 will continue its rotation and the in 12 when at the end of thegroove will e directed over the elevated bottom portion 11 thereof backinto the front end of the last of the outer convolutions of the groove.This is repeated until the machine is stopped by hand, or if it isdesired to continue the running of the machine the control rod 31 ismoved by the operator first in one direc tion and then the other atdesired intervals to shift the clutch sleeve 3 and cause the cylinder tobe successively driven in first one direction and then the other.

I wish it understood that my invention is not limited to any specificconstruction, arrangement or form of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims.

Having thus described my I claim as new, and ters Patent, is,
